Neutral atoms get smaller as you move across the periodic table from (left to right) because the atom increases in electrons. The more electrons, the bigger the effective nuclear charge (electron and proton attraction) and so basically the atom shrinks.
Answer:
200 lb•ft/s
Explanation:
From the question given above, the following data were obtained:
Force (F) = 2 tons
Time (t) = 5 mins
Height (h) = 15 ft
Power (P) =?
Next, we shall convert 2 tons to pound. This can be obtained as follow:
1 ton = 2000 lb
Therefore,
2 tons = 2 × 2000
2 tons = 4000 lb
Next, we shall convert 5 mins to seconds. This can be obtained as follow:
1 min = 60 s
Therefore,
5 mins = 5 × 60
5 mins = 300 s
Finally, we shall determine the power of the pump. This can be obtained as follow:
Force (F) = 4000 lb
Time (t) = 300 s
Height (h) = 15 ft
Power (P) =?
P = F × h / t
P = 4000 × 15 / 300
P = 60000 / 300
P = 200 lb•ft/s
Thus, the power of the pump is 200 lb•ft/s
Answer:

Explanation:
<u>Step 1: Define</u>
Scandium (II)
Cl
<u>Step 2: Determine Charges</u>
Sc²⁺
Cl⁻
<u>Step 3: Predict Compound</u>

RxN: Sc²⁺ + Cl₂ → ScCl₂
Answer:
24.305 to the nearest thousandth.
Explanation:
That is 0.7899*23.985 + 0.10* 24.985+0.1101*25.9825
= 24.305.
